摘要: 试验旨在分析研究乌珠穆沁草原饲养澳大利亚黑安格斯肉牛肌内脂肪酸含量和组成,为今后该品种的饲养改良、杂交繁育及肉品质的提高提供科学的基础数据.试验采集7头体重为(500±38)kg澳大利亚黑安格斯肉牛的里脊、臀肉、肩肉、眼肉、上脑、胸肉和米龙等不同部位肉样,采用简单高效脂肪酸提取方法,用气相色谱仪测定脂肪酸组成与含量,并与FAO/WHO推荐值比较,进行脂肪酸营养价值分析.结果表明黑安格斯肉牛不同部位牛肉中饱和脂肪酸(SFA)含量由多到少顺序为里脊、上脑、眼肉、肩肉、胸肉、臀肉及米龙,皆以棕榈酸和硬脂酸含量为主;单不饱和脂肪酸(MUFA)中油酸含量最高;检出的多不饱和脂肪酸(PUFA)多为亚油酸和亚麻酸;臀肉P/S和M/S最高,n-3/n-6 PUFAs比值达到0.85,接近FAO/WHO推荐值.以上结果表明乌珠穆沁草原饲养的黑安格斯肉牛的肉质风味良好,有较高的营养价值.

Abstract: Intramuscular fatty acids content and composition of Australian imported Black Angus beef raised in Ujinmqin grassland were analysised in this experiment to provide basic data for future breeding,crossbreeding,and meat quality evaluation.Target samples were taken of tenderloin,nates,shoulder clod,ribloin,highrib,brisket and topside from seven Black Angus beef which were Australian imported and raised in Ujinmqin grassland,with mean weights of (500±38)kg.The high efficient fatty acids extraction method and gas chromatograph (GC) were used to determine the content and composition of intramuscular fatty acids.Then the resuls were compared with FAO/WHO recommended values.The results showed that,the SFA content in target samples of Black Angus beef followed from high to low as:tenderloin,highrib,ribloin,shoulder clod,brisket,nates,topside.Moreover,majorities of intramuscular fatty acids composition were palmitic acid and stearic acid.The most highest content in MUFA was oleic acid;large amount of linoleic acid and linolenic acid were found in PUFA;The highest ratio of P/S and M/S were shown in nates,and the ratio of n-3/n-6 was 0.85.It was concluded that the meat of Australian imported Black Angus beef raised in Ujinmqin grassland had good flavor and high nutritive value.

Key words: Black Angus beef; meat quality; intramuscular fatty acids composition; analysis
